VALVE ADJU$TER.

Application filed October 10, 1823. Serial No. 657,783.

To all whom it may concern.

Be it known that I, CHAUNCEY E. Bron- ARDSON, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Valve Adjusters, of which the following is a specification.

This invention relates to gasoline engines, but more especially to those accessories known as valve adjusters and silencers, used in correcting the effects of wear which occurs in the tappethead, from frequent contact of the valve-stem thereon.

The principal objects of the invention are to provide a means for taking up the wear in the tappet-head, which can be economically constructed from one piece of material and conveniently installed, either in units or multiples.

To these ends, there is provided a disk, preferably of thin metal, having, integral therewith a gripping device capable of retaining said disk in place on a tappet.

In the drawings, Figure 1 is a side view of a disk as herein described, held in place by a spiral clip, on a portion of a tappet. Figure 2 is a plan view of the blank from which Figure 1 is formed. Figure 3 is a side view of a disk provided with clips at right angles thereto. Figure 4 is a plan view of the blank from which Figure 3 is formed; and Figure 5 is a top view of Figure 3. Figures 6, 7 8 and 9 are modifications of the invention, exhibiting various types of clips and means for attaching and retaining a disk in place.

The numerals 1, 1, 1 and the numeral 4 designate the disk proper; 2 and 2 are lips slightly projecting from 1; and 3, 3, 3 and 5 designate clips of several types.

Metal disks placed between the tappet and valve-stem for the purpose of correcting the effects of long-continued contact therebetween have been used for some time; but the task of retaining said disks in place has entailed the employment of cooperating separate parts, unnecessary expense, and more or less difficulty in installation, especially when a plurality of disks were required. The device herein described, being integrally formed, is installed with perfect facility and accuracy, and one can be conveniently disposed upon others without detracting from the effect and utility of either. Its manu facture is by a simple mechanical operation, and, in economy, it obviously possesses great advantages over those devices having separate parts.

To make this device operative, it is necessary to only slip it over the head of a tap pet, the clips 8, 5, serving to permanently retain it in place. If others are required, they can be placed over the first, the clips being slightly diverted from the positions of those first used. The extensions 2, designated as lips, are employed in Figures 3 and 9, to further facilitate this use in multiples without the interference of one with the others.

The helical clip 5 shown in Figure 1, although being composed of a single curl, is hereinafter referred to as clips, as its greater length gives it the same properties as those possessed by two or more clips. The clips which consist of spiral tentacles may be drawn or pressed so as to present flat surfaces to the tappet with which they contact, or they may present their edges to said tappet, as desired. Other changes and alterations are possible, with perhaps many variations, under this invention, without departing from the spirit thereof.

I claim:

1. A valve adjuster, comprising a disk, slitted to form a plurality of peripheral flanges integral therewith, said flanges being capable, when turned at an angle to said disk, ofattaching said disk to the object upon which it, is applied.

2 A valve adjuster, comprising a disk, slitted to form a plurality of peripheral lips and flanges depending from said lips, said lips and flanges being capable, when turned at an angle to said disk, of attaching said disk to the object upon which it is applied.

3. A valve adjuster, comprising a disk with lips projecting therefrom, clips integral with said disk and lips, and said clips being concaved to conform to the convexity of a tappet to which they are capable of being attached.

4:. A valve adjuster, comprising a disk with lips projecting therefrom, clips integral With said disk and lips, each of said clips curved spirally around a portion of a circle and capable of attaching said disk to a tappet.

5. A valve adjuster, comprising a disk,

. and, integral therewith, a spiral depending therefrom, and said spiral being capable of I retaining said disk to the tappet on which OHAUNOEY E. RICHARDSON.
